Smiling through the pain: Kara Tointon puts on a brave face following rumours surrounding her relationship with Artem Chigvintsev

She is reported to be less than happy about her boyfriend's latest dance partner, but Kara Tointon looked anything but insanely jealous as she went shopping yesterday afternoon.

The former EastEnder's actress is allegedly feeling extremely envious of Artem Chigvintsev's partnership with Holly Valance on this year's Strictly Come Dancing - but she's certainly not showing it.

Kara - who won the reality TV show last year after dancing with the Russian pro - struck up a relationship with him during the eighth series and confirmed it at the beginning of this year, but now it seems that their romance is under strain.

Artem was apparently reduced to tears after an emotional argument with 'insecure' Kara a few weeks ago and has been struggling to keep his emotions in check during rehearsals with former pop star, Holly.

But the 28-year-old showed no signs of her jealous side as she arrived at a large Tesco store to do some Sunday shopping.

Wearing a pair of black leggings with matching knee-high boots and a faux fur-detailed jacket, the actress looked happy and relaxed as she chatted away on her mobile phone.

She kept her large sunglasses on at all times and pushed her trolley - full of two reusable shopping bags - towards her car whilst still talking on her phone.

Reports have suggested that 29-year-old Artem moved out of the couple's home temporarily due to them having such bad arguments, but Kara appeared to be doing a food shop to stock up the fridge in their love nest, so perhaps all has been resolved.

Aussie star Holly has spoken up about the rumours and insisted that her and her dance partner are just good friends.

'We get on great and he is a fantastic teacher,' she said. 'But when you are suddenly spending time with a random man, it's important that everything is above board.'

The singer also added that she has been taking tips from former dancing queen, Kara.'Kara has been giving me lots of advice,' she said.

'It's not long ago that she did it and she knows what I am feeling like. That's been so brilliant.'
